Abstract (en)

[origin: EP4336686A1] In a gas-insulated switchgear configured by connecting a plurality of units each including a plurality of devices accommodated in a tank (50), a connection structure (60) connected with a power cable (20) is installed outside the tank (50) on both sides sandwiching a connection point between the units and a connection point between the devices. The connection structure (60) includes a cap (70) that closes an opening of the tank (50) and a plug (80) fixed to an outer surface of the cap (70). The cap (70) includes a cap conductor connected to a center conductor (52) and a cap solid insulator surrounding an outer peripheral side of the cap conductor. The plug (80) includes a cylindrical plug solid insulator and a plug conductor that closes an end portion of the plug solid insulator and is in contact with the cap conductor. A plug hole is formed on the plug conductor, the power cable (20) passing through the plug solid insulator is inserted into the plug (80), and a core wire of the power cable (20) is inserted into the plug hole.
